Stories created when a writer doesn't have any good ideas, but wants to write a story anyways. Usually the writer hopes, that even if it doesn't make sense to him/her, there will be readers who will find ways of analyzing and making it make sense in their lives.
Reader one: Can you believe the depth to that story about the penguin?
Reader two: I'm pretty sure that was all just story drool. It meant nothing.
You have no idea what you're talking about, you're just story drooling.
